A cover plate for an airbag module, such as a driver side airbag module. The cover plate includes a cover part and at least one wall which extends in a generally perpendicular manner in relation to the cover part. In order to prevent indentation areas from forming on the visible surface of the cover part on the transition points towards the walls and to provide the simple deformation of the airbag cover from the production tool, the wall extends, when seen in the cross-section thereof, at distances which are short in relation to the length of the wall, alternating in different directions.

Cover plate for an airbag module

An airbag covering cap including a support layer and a covering layer of different elasticities, having at least one tear-off line along which the airbag covering cap tears open when the airbag is deployed. The covering layer is weakened by a groove in the region of the tear-off line and the support layer extends into this groove. The covering layer has a section adjacent to the section of the support layer, which extends into said support layer. The edge between the sections of the support and covering layers, each extending into the other layer is configured as a tear-off edge.

Airbag covering cap comprising a support layer and a cover layer of different elasticities

A covering device for air-bag-collision-safety systems, including a cap formed of a frame and a cover. The cover is provided with predetermined tear lines forming cover sections, whereby the cover sections are connected in a hinge manner with the frame. The covering device is injection molded of a foamed thermoplastic material, especially an elastomer. Areas of various layer thicknesses lying in the gripping area of the user, such that the surface layers lying in the gripping area of the user, as well as the areas of the covering device used for attachment have a lower pore volume and correspondingly a higher density and hardness between 50 Shore A and 75 Shore D. A layer having a characteristic foamed structure is formed under the surface layers lying in the gripping area of the user, whereby the thickness ratio between the thicker surface layer and the foamed structure is 1 at the most. The foaming takes place while the volume of the mold is stepwise or continuously increased, whereby either the mold halves are separated on a preset path while the pressure in the mold is correspondingly reduced, or parts of the mold are drawn back in the cavity at certain preset points while the pressure in the mold is correspondingly reduced.
